The working surface of a clean chilled roll shows the white, graphite-free structure of eutectic carbide and transformed austenite. This gives a hard layer with good resistance to wear.
Compared with grey iron, white chilled iron is less strong and cannot withstand high dynamic stresses. But its greater hardness gives it better wear resistance and high compressive strength, and it keeps a fair proportion of its strength at elevated temperature.
The depth of chill is uniform, which makes these rolls highly dependable. They are classified into hardness categories to suit different applications.
A uniform depth of chill makes these rolls highly dependable, heat after heat.
